He says his patch should enter next release, but since on Mox this caused a regression, I would like it to be merged now. Anyway if you want to still wait for Miquels review to be sure, I am ok with that. What do you think about the "arm64: dts: armada-3720-turris-mox: add firmware node" which I sent last month?
